A nonexistent movie scene

Some time ago, I had a dream about an Errol Flynn movie which (as far as I know) does not actually exist. Flynn's character was a 16th-century English nobleman who fell victim to a string of events that resulted in the deaths of his entire family and his either being exiled on false charges or forced to flee the country. Some time later, he returned to England incognito to avenge his family and bring the villain to justice.

My dream was specifically about the scene where the disguised hero visits his family's graves. The cemetery's caretaker laments the ruin of such a noble house, and the hero replies something along the lines of, "Never assume the fire is out until the last spark has been extinguished."

I am very disappointed this movie isn't real. I'd watch it.
